HHT1,HHT2 (P61830) - Overview - Molecular Target Synopsis

Protein


HHT1,HHT2, Histone H3
UniProt P61830

Also Known as H3_YEAST, HHT1,HHT2, SIN2

Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Component of the UAF (upstream activation factor) complex which interacts with the upstream element of the RNA polymerase I promoter and forms a stable preinitiation complex. Together with SPT15/TBP, UAF seems to stimulate basal transcription to a fully activated level. The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA. Histone H3 is a component of the UAF (upstream activation factor) complex, which consists of UAF30, RRN5, RRN9, RRN10, and histones H3 and H4.
